How does the Pilot steer?

The aerodynamic surfaces (wings and tail) generate aerodynamic forces. Any object in flight will rotate about its center of gravity, the average location of the weight. Because the aerodynamic forces are applied at some distance from the center of gravity, a moment or torque is generated. A moment is a twisting force. The aerodynamic surfaces have moving parts which are controlled by the pilot and allows the pilot to vary the amount of force and moment which is generated. By changing the shape of the aerodynamic surface, the pilot can cause the aircraft to twist in flight.
